Insanity runs in the family. When you’re a lumberjock – you get better at the easy projects. You learn, your eye gets better, the nuances start to make sense. The more you do, the more nuances you are aware of. You learn, and learn and learn. Every now and then, you just take a giant leap right off the cliff and hope you land in a cushy spot. I was praying for that cushy spot on this one.

I’ll tell you all something from the heart – there is no way I could ever fathom a project like this before I met you all. You encourage the heck out of me. You give fantastic advice. You have made my simple projects so much easier. And once again, you have equipped me with enough know how to leap off that cliff. I don’t know if I’m making expensive firewood but I do know that you all just might rescue me before I hit the rocky bottom. I do know that I have friends I can count on right here.

Although so many of you have been a major source and help, I want to give a shout out to John, Klaus and my ever present friend Len. You guys have been making a big difference in my woodworking lately. Thank you guys so much!

I promise to hook up all the blogs and links to the projects that gave me a major head start on this one. In the meantime, it’s dinner time and my wife is about to skin me if I don’t get in there now. ;)

-- Thanks for all the lessons!

I’d love to see the jigs that make those parts possible! My brain is coming up with all sorts of ideas now.

I discontinued the blog at a certain point. That’s about the time I started experimenting. Still – the blog will get you all the way to making the complete soccer ball shape.

Clamping was a bit of an exercise but Gorilla tape saved my life. That’s about it my friends. Thanks for letting me stand on your shoulders.

Von – go to town man. I’d love to see your stuff! I attached the blog. All I used was half sleds with bevel cut kerfs. I added a pic of one of them to the blog. I didn’t use jigs for clamping because I found a way to draw the pieces together tightly. It involved tape and Irwin clamps.

Steve. Thanks for the compliment sir!

Lightning – thank you sir! ;)

Can you do that with dovetail joints? ;-) Just being facetious, again. Awesome and impressive work!

Carver, I have a headache right now. It’s was so hot yesterday that I’ve had a headache all day today. ;)

Howdy Jim, I see you found the blog. It’s not so bad unless your angle is off by .01 degrees. Good lord those cuts are unforgiving.

I love them Mark.
I’ve had a go at that kind of thing myself, .... it makes the old brain smoke a bit.

Nice work !

You were a lot of help. I’m especially fond of the glue up tricks you shared with me. I’m very grateful for that.

I remember that dodecahedron box. Beautiful and mind blowing. Thanks for the generous comments.

Just for you my friend – all the links to the “how to” is above. Enjoy!

Thank you kindly sir.
